Expertise
Skills & Specializations
What eight years taught me.
Six areas I can defend in an interview, from architecture to production AI.
LLM-Powered Applications
Intelligent Agentic Workflows
I integrate OpenAI and Gemini into full-stack products that people use every day: AI workflows, real-time generation, and agentic systems designed to fail safely and ship on time.
React & Next.js Architecture
Scalable UIs & Micro-Frontends
I design frontend systems that scale: component libraries, deliberate rendering strategies, and micro-frontends with Module Federation. Architecture decisions that keep large codebases fast and teams unblocked.
Full Stack & BFF Patterns
Node.js, GraphQL & NestJS
End-to-end ownership, from database schema to API contract. I design Backend-for-Frontend layers that keep UI needs separate from service complexity: typed, versioned, and tested in production.
Architecture for Large Teams
Governance & Scalable Infrastructure
I have worked inside large Agile teams serving global users. I build governance models, code review standards, and shared infrastructure so teams move fast without breaking things.
Testing & Delivery Pipelines
Automated QA & Deployment
Quality is part of the build, not a phase at the end. I write Jest, React Testing Library, Cypress, and Playwright tests into GitHub Actions pipelines so releases stay boring and safe.
WCAG & AODA Compliance
Inclusive & Accessible Design
Accessibility is built into my components, not bolted on at the end: semantic HTML, ARIA patterns, keyboard navigation, screen reader testing. Every release stays compliant by construction.

Work That Speaks
For Itself
A selection of projects showcasing my expertise in building performant, scalable, and user-focused applications.
Preplify: AI Interview Prep
Production multi-provider LLM interview platform on Next.js and TypeScript: OpenAI and Gemini behind one orchestration layer, GraphQL for relational data, REST for AI workflows, WebSocket-driven sessions. AI interviewer: practice with an AI, get structured feedback. Outcome: failover-safe AI that degrades gracefully instead of failing loudly.
Service Management Platform
Enterprise micro-frontend platform for aviation operations: one shell, independent domain teams deploying through Webpack Module Federation, shared design system, governed releases. Outcome: independent teams shipping to one shell without breaking each other.
Cyber Mart
Multi-vendor marketplace on Next.js and Node.js/Express: MySQL for transactions, MongoDB for catalog content, per-route rendering (SSR/ISR/CSR), hardened checkout. Outcome: full-stack ownership, from index strategy to checkout.
Chalet Retreat
Luxury rental platform on Next.js and TypeScript: map-based discovery with clustering, layered image optimization, multi-step Stripe booking. Outcome: craft under constraints, rich media with fast pages.
Class Ops
Classroom management platform with a rigorously modeled relational core and role-based portals for admins, teachers, and students. Outcome: domain-modeling rigor for multi-role systems.
OOGO
Bilingual UAE marketplace with structural RTL architecture: layout, navigation, and typography invert for Arabic, not just text. Three portals share one Redux entity layer. Outcome: localization as architecture, not translation.

FAQ
Got Questions?
I Have Answers.
Have questions about working with me? Here are answers to the most common inquiries I receive.
What kind of work are you looking for?
Senior full-stack roles, remote or contract, where I can ship AI-integrated products inside an existing enterprise team. I am based in Toronto, Canada.
How do you add AI to an existing product safely?
I treat the LLM like any external dependency: behind a stable internal interface, with failover, retries, and grounded prompts. The existing system keeps working even when the AI provider does not.
What is a typical timeline?
It depends on scope. I work in weekly increments with a demo you can click, so you see progress early and can change direction cheaply.
Do you work across time zones?
I overlap North American working hours from Toronto and keep async updates tight for teams elsewhere.
How many projects do you take on at once?
I keep my focus narrow so each engagement gets senior attention, not spare hours.
How do we start?
Send a message through the contact form. Then a short intro call, then a written proposal with scope, timeline, and price. No obligation either way.
